GPU hardware acceleration as the most eye-catching features of the IE9 browser, the major browsers also continue to introduce this function. Many users also want to experience how much this feature can improve browser performance. However, after installing the IE9 beta version, I found that the GPU hardware acceleration could not be turned on, and the "use of software rendering without GPU rendering" could not be canceled. The user's computer graphics card is Intel GMA 3150, the use of Windows 7 with the driver does not, to the Intel official website download to use the latest driver is not good, this is what reason?
To experience this feature of the IE9 browser, there is also a need for computer hardware, IE9 hardware acceleration needs to support more than 10 of DirectX graphics cards, Intel GMA 3150 graphics only support DirectX9. So the default selection is "Use software rendering instead of GPU rendering."
According to this, NVIDIA Geforce 7600GS is not supposed to support GPU acceleration. However, this option is not grayed out and is not checked, which means that IE9 is enabled for GPU acceleration.
Later, through communication with Microsoft staff, this is really about the graphics card. There are several types of video cards that are currently known to not support the browser GPU hardware acceleration, and you can compare the following:
Intel GMA, GMA 3150, 82945G Express, G33/g31, Mobile 4 Series Express, HD Graphics
VIA Chrome9 HC3
AMD DirectX 9 Adapters (ATI RADEON X1950)
ATI Mobility FireGL V5250 & V5700
Very old (Windows vista-era) Nvidia GPUs
Unfortunately, we can see that GMA 3150 is explicitly in the unsupported list.
If your IE9 cannot turn on GPU hardware acceleration, check your video card for an unsupported list, or a video card below DirectX 10.
